This is the one I now have on my Predator GS with the G231 - I find it guieter, more mellow sounding and more powerful then two others I have used before.

TSK, I haven't heard that brand namefor years. I retired my TSK MyStar GS when I got the Predator 3 or 4 years ago - the Predator flies like a sport car (great for 3D) while the MyStar (great precision machining etc.) flew like a station wagon. I think the gearing and Tanaka motor that TSK supplied with their GS were the culprits. The Mystar was a great heli design. I loved my Mystar 60 which was a far better flyer then the gasser version.

On the other hand, I found the Preddy was evenmore stableand yet moreagile then the MyStar 60!!!
